Democrats and Republicans sparred Sunday over President Obama's signature health-care law, as Republicans kept up their criticism of its problems, and Democrats sought to champion its core components.

"This is a rollout problem. This is not a values problem," said Rep. James Clyburn (R D-S.C.) on CNN's "State of The Union."

"The president said he fumbled the rollout. It's time for a timeout which I've been calling for so we can go back to the drawing board," said Sen. Kelly Ayotte (R-N.H.) on NBC's "Meet The Press."
